Night has fallen and I'm running across rooftops, as always, trying to see if there's any enemies doing things they shouldn't.

"BOOYAKASHA!"

"What in the world?" I say skidding to a halt and turning at the sound of the voice.

*bang bang pew pew bang crash*

Purple lasers flying everywhere?

I decide to investigate, peering over the building, and what I see surprises me.

(Are those robots with brains inside of them? What the hell is kicking their asses? Omg! They're turtles!? They aren't my sisters though. I didn't know that there were others.)

They quickly finish the rest of the robots.

"Leo, watch out!" the purple masked one yells.

I watch as one of the robots are about to shoot the blue one's head from behind and throw a ninja star through its head, causing it to tumble before the blue one turns around.

"Thanks for saving my shell, Donnie!" the one calls Leo yells back.

"I didn't do anything," the one called Donnie says nervously.

"It came from up there!" the orange masked one yells and points in my direction.

(Ah shit!)

I quickly duck away and run away across rooftops.

"BOOYAKASHA!"

I dodge the on coming sickle chain by jumping up, grabbing it, and throwing it right back at its owner.

I flip off the roof side to underneath a balcony to hide. I watch as they all fly pass me to the ground.

They land without a sound and look around.

"Who was that?" the orange one comments.

"I don't know. I didn't get a good look at em," the red one says.

"We'll be staying on patrol a while longer than usual," Leo comments.

"Seriously!" the red one complains.

"We have to find this mysterious person," Leo says. "Sorry, Raph."

(I'm not a person!)

"Urghh..." the red one named Raph complains.

"Whoever you are if you're still here, thanks for saving my shell back there," Leo shouts out.

"If you come out we won't hurt you!" Donnie says.

I snicker inaudibly. (No way in hell I'm coming out.)

"I don't think they're coming out that easily, Donnie," the orange one says. "You have to do it like this... Hey, whoever you are we just wanna make sure you aren't an enemy and be your friend! We are the good guys!"

(I'm not an enemy and I'm not gonna fall for something so stupid!)

"I don't think that's gonna work either, Mikey," Donnie says.

I quickly scribble something on a ninja star and throw it at the wall behind them.

"Whoa! Did anybody see where that came from?!" Mikey yells.

"No," Raph says annoyed.

Donnie walks over and plucks the ninja star from the wall.

"It says 'I'm not an enemy, so don't worry.'" Donnie reads.

"Then come out and prove it," Leo says.

(Bitch...) [I'm not proving shit. My word should be enough.] I use my bow and arrow to throw down another star when nobody's looking with that written on it.

"'I'm not proving shit. My word should be enough.'" Donnie reads.

"That's a shitty way to go by," Raph says.

I could go for beating up some foot soldiers right about now... These guys are starting to annoy me.

"How do we know if you don't show us," Leo says.

"How do I know that you aren't evil?" I finally say then quickly change my position to a different location without them noticing.

They all turn to look at my previous location.

"It's a girl," Donnie says.

"What a great observationist you are," I reply sarcastically, changing location.

They turn again.

"Stay in one spot, will ya?!" Raph yells.

"I'm sorry, am I making little Raphy upset?" I tease and move.

"Don't call me that!" Raph yells.

"Anyway, shouldn't me saving the leader's life proof enough?" I ask. "Right, Leo?"

"How do you know our names?" Leo asks.

"Don't answer my question with a question!" I yell, moving again.

"Fine... it's enough for now," Leo says. "Now answer my question."

"Bakas... You've been saying them constantly," I say and move.

"Who are you?" Donnie asks.

"I'm sorry, but that information is classified, Donnie," I say, moving again.

"Ooo ooo, my turn next! What's my name?!" Mikey exclaims.

I laugh. "Mikey."

"Yay! She got it right!"

"I don't think that's such a great thing, Mikey," Donnie says with a sweat drop.

"Since you know our names, why can't we know your's?" Raph asks, a visible tick mark on his head.

"As much as I would love to tell you I'm not going to. Is Raphy getting angry?" I ask.

"Damn right!" he yells and launches himself at me.

Of course, I move, unnoticed, and flip, kicking his chest and in result throwing him down straight to the ground.

"Raph!" they all yell.

"It doesn't seem like you're a good guy, I mean, girl to me," Leo says.

"What? I was just defending myself. He started it, Mr. Anger Issues," I mutter.

"Come out," Leo growls.

"I don't wanna surprise you," I say. "Because when I saw you I was in for quite a shock. Hell, I'm still shocked."

"What do you mean?" Donnie asks.

"I mean how common is it to find someone, or someones which is more shocking, who looks exactly like yourself," I say.

"Wait, do you mean?" Donnie asks.

I laugh. "That's for me to know and you to find out. See ya!" I yell and dash away while they're distracted by helping Raph. "Tell Raph I'm sorry!"

~Leo's POV~

"Are we gonna watch or go after her!?" Mikey yells.

"I have a feeling we will see her again, right now we need to help Raph," I say. "We'll talk about her later."

"He's got a few cuts from the fall and unconscious from the impact," Donnie says. "We need to take him to my lab so I can fix him up."

"I'll hold him up from the left if you take his right," I say. "Mikey open the manhole cover."

"Sir!" Mikey says and opens it, holding it open for us.

"I'll go down first so you can hand Raph to me," I say and hand Raph over to Donnie and get down first.

~~~

We make our way down to the lair and Donnie fixes Raph up and now we're all in sensei's room except Raph.

"What happened to Raphael?" Splinter asks.

"We met a new person!" Mikey says. "I've named her Mysteria because we don't know who she is or what her name is!"

"Enemy?" Splinter asks.

"She said that she wasn't. She even saved my head from being shot off from a Krang bot," I say.

"She knows how to fight too," Donnie says. "Raph figured that out the hard way when he attacked her."

"I see," Splinter says, stoking his long beard.

"She also said something that I found interesting when Leo told her to come out," Donnie says.

"And what would that be, my son?"

"She said and I quote 'I don't wanna surprise you. Because when I saw you I was in for quite a shock. Hell, I'm still shocked.' Then I asked her what she meant and she said 'I mean how common is it to find someone, or someones which is more shocking, who looks exactly like yourself,'" Donnie says. "Then she left."

"That is interesting," Splinter says.

"So she means that she's a teenager too!" Mikey says.

"No, it means that she's a mutant like us," I say.

"Even better!" Mikey exclaims.

"Do you think she could be working for the Kraang or Shredder?" I ask sensei.

"Possibly," he responds. "Keep a lookout for her. She could pose as a threat."

"Yes, sensei," we all say and bow our heads.

We leave the room and head into our own rooms.

I can't help but wonder, what did she mean exactly, before I fell asleep.
